Cumulus customized quilt 150 or x-lite 200 are far better. How I know? I own a 2023 mythic 600 wich made me realize that in any photo you see from a rab sleeping bag you're watching a super overfilled bag, they aren't that lofty, the baffles looked 70% filled, just spend the money buying it and you'll see it by yourself🙄 They could at least give the option to customize it and overfill it to sell the same thing they show at the photos😑 Not to talk about their comfort limit wich they state at least 3°C lower than its true limit, I am a warm sleeper, and even having a good dinner I didn't sleep well at 0°C over a thermarest Xtherm They do one thing better than anyone! Marketing and propaganda👏🏽👏🏽👏🏽
